Patented July 29, 1947 UNITED STATES PATENT OFFICE POSTHANDLING JACKLawrence A. Haney, St. Paul, Minn; Application october 3, 1946, SerialNo. 700,872 2 Claims.- ((1254-1 32) The present invention relates to anovel and improved manually operated mechanical jack which is expresslydesigned for handling posts and the like.

More specifically, the invention has to do with a simple, practical andeconomical jack for perpendicularly lifting and lowering heavy fenceposts, principally metal posts, the preferred embodiment of theinvention being characterized by a stand, a swingably mounted cant hookto embrace the post, and means for operatively mounting said hook onsaid stand.

More particularly, the invention comprises a stand having a flat baseplate with an accommodation notch to receive and guide the post, anupright on said base, a lever fulcrumed on said upright, a cant-hook,and linkage connecting the hook with an adjacent operating end of saidlever.

One phase of novelty is thought to reside in the notched base plateprovided with a simple upright structure made up of a pair of angleirons vertically disposed and spaced apart and connected at their upperends and provided at said upper ends with a bail-like hand-grip.

Novelty is also thought to reside in the adoption and use of a simpleand expedient horseshoesh'aped cant-hook and the specific means wherebyit is operably mounted on said base plate and centered over the postguide notch in said base plate.

Other objects, featutres and advantages will become more readilyapparent from the following description and the accompanyingillustrative drawings.

In the drawings:

Figure 1 is a side elevational view of a post lifting and lowering jackconstructed in accordance with the principles of the instant invention,

Figure 2 is a top plan view of the same,

Figure 3 is a front elevation, that is a view observing Figure 1 in adirection from right to left, and

Figures 4, 5 and 6 are perspective views of different types of postswhich may be handled with a jack of the type shown and described.

Referring now to the drawings by distinguishing reference numerals, itwill be seen that the portable stand is denoted, generally speaking, bythe numeral 8 and comprises a substantially rectangular base plate 9having a notch in one perimeter edge, said notch indicated at l0 andserving as an adaptor and guide for the post A. The notch permits thebase plate to be shoved up against and to partly surround the post inorder to facilitate the post handling steps. The upright means orstandard is denoted by the numeral ll and this comprises a pairofvertical spaced and parallel angle irons l2, these rigidly connected attheir lower ends to the central region of the base plate. The upper endsof the angle irons are connected together by a head or cross-piece l3provided with a bail-like handgrip I l. The numeral [5 designates ahorizontal fulcrum pin which is removably mounted in the upper endportions of said angle irons. This pin serves to accommodate a simplelever 16 which may be formed integral with the pin, or which may berockably mounted on the pin, as desired. The operating handle for thelever is denoted by the numeral I1 and is provided with a socket l8fitting over the lever. Suitable length handles may be employed ispractice depending upon the leverage wanted and the conditions oflifting, lowering and weight handling met by the user.

The post engaging cant-hook is denoted by the numeral l9 and as beforestated is of general horseshoe-shaped form and embraces the post and islocated directly over and moves up and downin alignment with the notchID. This hook is provided ononeside with a lug 20 pivotally pinned, asat 2|, between the lower ends of spaced parallel links 22 which are, inturn, pivotally pinned, as at 23, to the adjacentoperating end of saidlever IS.

The jack means shown and described lends itself adaptable to handlingvarious types of posts, that is metal posts of varying cross sectionalshape. In Figure 1, I have shown a post A which is cylindrical in crosssection. In Figure 4, there is a post B which is rectangular in crosssection. In Figure 5, I have depicted a so-called T-shaped post C, whilein Figure 6 I show an ordinary, sometimes used, angle iron post D.

It is submitted that the invention shown and described is aptly suitedto achieve the ends sought, is characterized by a combination of highlyuseful and mutually cooperable expedients and that the latter combinetheir assistive and proportionate functions in enabling the user toreadily position the stand and cant-hook and to then, with a minimum ofeffort, dislodge and lift a heavy post in a practical and convenientstep-by-step manner. The invention is primarily useful in withdrawingposts from the ground but, of course, may be employed in the initialstep of setting the posts in post holes provided in the ground.

A careful consideration of the foregoing description in conjunction withthe invention as class described, a base plate, an upright structure; onsaid base plate comprising a pair of per-,

pendicularly arranged and spaced angle irons, a rigidly attachedcross-piece mounted atop and securing the upper ends of said angle,irons together, hand-grip fixedly carried by said crosspiece, a leverfulcrumed between the upper end portions of said angle irons, ahorseshoe-shaped cant-hook adapted to tiltably embrace and frictionallygrip the post, a pair of links carriedv by, depending from and pivotallymounted on said lever, and a pivotal connection between the lower endsof said links and an adjacent portion of said cant-hook.

2. A post-pulling jack of the class described comprising a substantiallyrectangular fiat bottomed base plate provided on one marginal edge witha post accommodating and guide notch, upa right means mounted on thecentral portion of said base plate and embodying a pair ofperpendicularly disposed, spaced and parallel angle irons, a horizontalcross-piece mounted atop and secured rigidly to the upper ends of saidangle irons, a horizontal fulcrum pin mounted in the upper end portionsof said angle irons, and situated in parallelism beneath saidcross-piece, a relatively short lever fulcrumed intermediate its ends onsaid fulcrum pin, one projecting end portion of said lever being adaptedto accommodate a detachable socket-equipped handle, a pair of linkscarried by, depending from and pivotally mounted on the opposite end ofsaid lever, a rigid heavy-duty horseshoe-shaped cant-hook situatedwithin the marginal limits of the base plate and aligned with andmovable toward and from said notch, one limb of said cant-hook beingprovided with a laterally projecting lug and said lug being pivotallymounted between the lower end portions of said links.
